Please go to the Downloads page for CSD 2 and try the new "CSD2_GOG_Mac_v2_60m1_1_2020.app.zip" file and let me know if that works. Thank you and apologies!
It did allow me to click on it and "open" it, but it just showed this:
This was after the file was extracted, correct? What macOS are you running?
Yes, this was after the file was extracted. I am using Sierra.
